Verbena plant named ‘Wesverrose’

ABSTRACT

A new and distinct cultivar of  Verbena  plant named ‘Wesverrose’, characterized by its cascading plant habit; ovate-shaped leaves; freely flowering habit; large inflorescences; and red purple-colored flowers.

Botanical classification/cultivar designation: Verbena hybrida cultivar Wesverrose.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘Wesverrose’.

The new Verbena is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the program is to create new Verbena cultivars with cascading growth habit and attractive flower colors.

The new Verbena originated from a cross-pollination made by the Inventor of a proprietary selection of Verbena hybrida identified as code number 99FAT8, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number 99FAT03, not patented, as the male, or pollen, parent. The new Verbena was discovered and selected by the Inventor from within the resultant progeny from the above-mentioned cross-pollination in a controlled environment in Südlohn, Germany in 2000.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Südlohn, Germany, since 2001, has shown that the unique features of this new Verbena are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Wesverrose’. These characteristics in combination distinguish ‘Wesverrose’ as a new and distinct cultivar:

-   -   1. Cascading plant habit.     -   2. Ovate-shaped leaves.     -   3. Freely flowering habit.     -   4. Large inflorescences.     -   5. Red purple-colored flowers.

Plants of the new Verbena differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have orange-red colored flowers. In addition, plants of the new Verbena have a more cascading plant habit than plants of the female parent selection.

Plants of the new Verbena differ primarily from plants of the male parent selection in flower size as plants of the male parent selection have smaller flowers. In addition, plants of the new Verbena have longer lateral branches and leaves that are more ovate in shape than plants of the male parent selection.

Plants of the new Verbena can be compared to plants of the cultivar Wesverdark, disclosed in U.S. Plant Pat. No. 13,847. However, in side-by-side comparisons conducted in Südlohn, Germany, plants of the new Verbena and the cultivar Wesverdark differed in the following characteristics:

-   -   1. Plants of the new Verbena had a more cascading plant habit         than plants of the cultivar Wesverdark.     -   2. Plants of the new Verbena were more vigorous than plants of         the cultivar Wesverdark.     -   3. Leaves of plants of the new Verbena were more broadly ovate         and had shorter petioles than leaves of plants of the cultivar         Wesverdark.     -   4. Inflorescences of plants of the new Verbena were more open         than inflorescences of plants of the cultivar Wesverdark.     -   5. Plants of the new Verbena and the cultivar Wesverdark         differed in flower coloration.

Plants of the new Verbena can also be compared to plants of the cultivar Scarlena, disclosed in U.S. Plant Pat. No. 12,578. However, in side-by-side comparisons conducted in Südlohn, Germany, plants of the new Verbena and the cultivar Scarlena differed in the following characteristics:

-   -   1. Leaves of plants of the new Verbena were broader than leaves         of plants of the cultivar Scarlena.     -   2. Inflorescences of plants of the new Verbena were more open         than inflorescences of plants of the cultivar Scarlena.     -   3. Plants of the new Verbena had larger flowers than plants of         the cultivar Scarlena.     -   4. Plants of the new Verbena and the cultivar Scarlena differed         in flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Verbena.

The photograph at the right of the sheet comprises a close-up view of a typical inflorescence of ‘Wesverrose’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Wesverrose has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Südlohn, Germany, under commercial practice during the spring and summer in a glass-covered greenhouse with day temperatures ranging from 20 to 25° C. and night temperatures ranging from 16 to 18° C. Cuttings were planted in 12-cm containers, pinched one time about two weeks after planting, and had been growing for about 20 weeks when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
